Reports are coming in thick and fast from all over the web that 3rd party Apple re-sellers are out of the Apple TV leaving many to speculate that they will announce a refresh tomorrow alongside the iPad 3 (or HD) announcement.

The current Apple TV only supports 720p video so many think Apple will introduce a 1080p version and perhaps even include "Siri" integration. I think this is unlikely as I don't think "Siri" will be introduced to an Apple TV product until Apple has finalised content deals with all the major networks.
